Hello,
Tim suggests checking that the figure of merit is not 0.0 (that is set in
the Peak List editor). And also check that in the Edit Spectra -->
Tolerances dialog that the shift weighting is 1. And check that the
experiment has a shift list. These are all remote possibilities but worth
double-checking. Otherwise send us the project without the spectra.
